Objective To observe the expression of P21 and CDK6in cervical squamous cell carcinoma,and to investigate the relationship between their expression and cervical squamous cell carcinoma.Methods The expression of CDK6 and P21in 100 cases of cervical squamous cell carcinoma,20 cases of cervical CIN lesions and 20 cases of normal cervical tissues were detected by immunohistochemical ABC method,and the relationship between them and tumor differentiation,invasion depth,lymph node metastasis and clinical stage were analyzed.Results The expression rates of P21 and CDK6in cervical squamous cell carcinoma tissues were significantly higher than those in CIN lesions and normal cervical tissues;The low expression of P21 was associated with the depth of tumor invasion,lymph node metastasis and clinical stage(P0.05),and was not associated with the degree of tumor differentiation(P0.05);The high expression of CDK6 was associated with tumor differentiation,invasion depth,lymph node metastasis and clinical stage(P0.05).Conclusion The abnormal expression of P21 and CDK6may play an important role in the occurrence and development of cervical squamous cell carcinoma,and the two may have a certain significance in the prognosis of cervical squamous cell carcinoma.
